i am getting ready to send my sons blaster jug and head to trenga for a top end machining. they recommend a pro x piston kit but all i have ever ran is wiseco pistons. is the pro x a forged unit like the wiseco? any help would be great. pete

 

IMO pro x is better, my pro x lasted alot longer than my wiseco did which was like 20 hours

 

you should rethink your options before you send anything of value to trenga, they are not the best for top end work on a blaster and never will be, ask some questions on the net to who is noted as the best engine shop for blasters and you'll find trenga is one of the worst for quality and customer service, I know this from experience.
